Healthy Aging After 40: How Does Asia Compare with the West?
Updated: Oct 10
How does your country compare - and what can you do for your next 10 years? Healthy aging after 40 starts with a personal plan. Explore the differences between selected Asian and Western countries, then turn that perspective into everyday habits.
Free 10-page visual guide: compare 11 countries across Asia and the West, explore three sourced infographics, and build your plan with five practical foundations and a seven-day worksheet.
Healthy aging in Asia and the West: how does your country compare?
In the World Bank / UN 2025 estimates, people aged 65+ make up 30.0% of Japan's total population, 23.7% in Germany, 20.3% in South Korea and 8.0% in Malaysia. The difference within Asia is substantial: a single Asia-versus-West average would hide it.
These selected countries are not regional averages. Every bar uses the same year, age threshold and total-population denominator. Singapore's citizen-only figures below use a different denominator. An older population does not establish better or worse individual health, or the effectiveness of a wellness product.
The download also shows how the age 65+ share changed from 2000 to 2025. South Korea's increase was 13.2 percentage points, compared with 3.8 in the UK. Add the full change infographic and seven-day worksheet to your own healthy-ageing plan.
What else differs across Asia and the West? The expanded guide compares lifespan with healthy life expectancy in eight countries, explains the pace of population aging, and explores food choices and care support. Each comparison includes an explanation and a practical takeaway for your own plan.
Singapore has just crossed a major milestone: it is now a super-aged society. In 2026, 21.4% of Singapore citizens were aged 65 or older, according to the government’s Population in Brief figures reported by The Straits Times. The figure refers to citizens, rather than all residents or the total population. [1][2]
But this is not only Singapore’s story. Across the world, more people are living into older age. The World Health Organization (WHO) projects that the number of people aged 60 and older will reach 2.1 billion by 2050, roughly twice the 2020 figure. [3]
There is another part of this story that deserves attention: many of the people living these extra years are women. A separate Straits Times feature on healthy longevity points out that women tend to live longer than men while spending more years with ill health. [11]
That raises a more personal question than any population chart can answer: What do we want our extra years to feel like?
Perhaps it is being able to walk around a new city, carry the groceries, cook a meal, remember a conversation, meet friends, or help a grandchild. Healthy aging begins with those everyday abilities.
In brief: Healthy aging means keeping the ability and support to do what matters to you as you get older. Movement, nourishing meals, preventive care, social connection and an accessible environment all contribute. There is no guaranteed shortcut.
What does “healthy aging” actually mean?
WHO describes healthy aging in terms of maintaining the ability to do the things that matter to us as we grow older. That ability depends on our physical and mental capacities and on the world around us: a safe home, accessible transport, supportive relationships and useful health services. [4]
In other words, a birthday does not tell the whole story. Two people of the same age may have very different energy, mobility, confidence and opportunities. A person can also live with a health condition and still pursue a meaningful, active life with the right support.
The goal is not to avoid birthdays. It is to preserve choice.

Why the world is paying attention now
Population aging is accelerating across regions. WHO estimates that one in six people worldwide will be 60 or older by 2030. By 2050, most older people will live in low- and middle-income countries, which makes access to affordable care and age-friendly communities a global issue. [3]
In Singapore, the share of citizens aged 65 and above rose from 13.7% in 2016 to 21.4% in 2026. The government projects that more than one in four citizens may be in this age group by 2035. That 2035 figure is a projection, not a certainty. [2]
These numbers matter because longer lives affect families, workplaces, housing and healthcare. They also create more opportunities for older adults to learn, mentor, work, volunteer and enjoy time with people they love. Whether those opportunities are available depends in part on health and in part on how communities are designed. [3][4]
Why healthy aging is also a women’s issue
Women account for about 54% of people aged 60 and older worldwide. At the oldest ages the difference is even more pronounced: in 2025, women made up 62% of the global population aged 80 and older, according to the United Nations. These are global figures, not percentages for Singapore. [12]
Living longer does not automatically mean living more years in good health. A longer life can bring more time with mobility problems or chronic illness, and older women are more likely than older men to live alone globally. Some also continue caring for a spouse, grandchildren or other relatives while managing their own needs. None of this describes every woman, but it changes the questions families and health systems should ask. [11][12]
Will she have the strength to move comfortably, the care she needs, people to call, and the freedom to decide how she wants to live? A serious conversation about healthy aging needs to make room for those questions. The same foundations below matter for everyone, with support tailored to each person’s circumstances.
How to stay healthy after 40: five practical foundations
There is no single routine that guarantees a healthy old age. The strongest starting point is a set of habits and supports that work together.
1. Move for everyday strength and maintain muscle after 50
Walking is useful, and so are strength and balance. Standing up from a chair, climbing stairs and carrying a bag all depend on abilities that can be practiced.
WHO recommends that older adults aim for at least 150 minutes of moderate physical activity a week, add muscle-strengthening activities on two or more days, and include balance-focused activity on three or more days where appropriate. Start from your own level; some movement is better than none. If you have a condition that affects your safety or mobility, plan the right activity with a health professional. [5]
Try this: Take a short walk after a meal, practice safe sit-to-stand movements, or join a suitable balance or strength class.
2. Make everyday meals work harder
Healthy aging needs ordinary food, consistently. A useful plate includes a variety of vegetables and fruit, whole grains, and protein foods such as fish, eggs, beans, tofu, dairy or other options that fit your culture and needs. WHO emphasizes a varied diet and limiting excess salt, sugar and less healthy fats. [6]
Try this: Before buying a new wellness product, look at the meal you eat most often. Could you add a protein food and a vegetable? If appetite, chewing or swallowing has become difficult, raise it with a clinician instead of simply eating less.
If your question is whether your current meals already cover your needs, read do you still need supplements if you eat well?
3. Pay attention to the problems that quietly narrow your world
High blood pressure and diabetes may not announce themselves in everyday life. Hearing, vision and oral problems can make conversation, movement and meals harder long before someone thinks of them as “aging issues.” Regular reviews help you notice changes and discuss what is worth addressing. WHO’s approach to care for older people includes attention to declines in mobility, hearing, vision and other capacities. [7]
Try this: Ask a healthcare professional which checks make sense for your age, history and country. In Singapore, Healthier SG Screening covers eligible cardiovascular and cancer screening; Project Silver Screen offers community-based checks of vision, hearing and oral health for eligible older residents. [8][9]
4. Protect connection as deliberately as fitness
Healthy aging is social. Isolation and loneliness are associated with poorer physical and mental health, while meaningful relationships can help people stay engaged. An association does not mean that every lonely person will become ill, but it is a good reason to make connection part of a weekly routine. [10]
Try this: Put one recurring conversation, shared meal, class or walk on the calendar. If transport or mobility is the obstacle, look for a nearby group or accessible option.
5. Make your surroundings support independence
A well-lit path, a safer bathroom, a walkable neighbourhood and reliable transport may do as much for day-to-day independence as personal motivation. WHO includes age-friendly environments and accessible care in its healthy-ageing work because individual effort cannot remove every barrier. [3][4]
Try this: Choose one friction point at home or in your routine. Could a better light, handrail, clearer medication list, transport plan or family arrangement make an important activity easier?
Do I need supplements for healthy aging?
Some people use supplements to address a specific dietary gap or follow professional advice. They are one possible part of a nutrition plan, not a substitute for food, movement, social connection or appropriate care. The useful question is specific: Which ingredient, at what dose, for which need, and supported by what evidence?
If you are comparing nutritional products, begin with your diet and the current product label. See our guide to everyday nutrition for a starting point, and discuss personal needs or interactions with your healthcare professional.
The question worth asking this week
Imagine yourself ten years from now. What is one thing you would still love to do without giving it up?
Now work backwards. If the answer is travelling, think about strength and balance. If it is sharing meals, think about nutrition, teeth and company. If it is continuing your work or hobbies, think about hearing, sight, purpose and support.
Healthy aging is not a promise that nothing will change. It is a practical commitment to keep more possibilities open as life changes.

Frequently asked questions about healthy aging
What is healthy aging in simple terms?
Healthy aging, also spelled healthy aging, means maintaining the abilities and support that help you do what matters as you get older. It includes physical and mental health as well as the people, services and surroundings in your life.
Why does healthy aging matter for women?
Women make up a majority of older adults worldwide, especially at ages 80 and above. They often live longer than men, but extra years do not always mean more years in good health. Support for mobility, care, finances and connection matters.
What makes a society “super-aged”?
The benchmark commonly used in Singapore’s population reporting is 21% or more aged 65 and above. Singapore’s 21.4% figure in 2026 refers specifically to citizens. Other population measures can produce a different percentage.
Is healthy aging the same as living longer?
No. Life expectancy describes how long people live on average. Healthy aging focuses on maintaining the abilities and support needed to do what matters during those years.
Can I still improve my health after 60 or 70?
Yes. Aging varies widely between people, and appropriate physical activity, a balanced diet, preventive care and supportive environments remain relevant in later life. Choose a starting point that fits your current abilities and conditions.
What should I do first?
Pick one action you can repeat: a short walk, two strength sessions a week, a more balanced meal, a health appointment or a regular meeting with a friend. Small actions become more useful when they fit real life.
How do I stay healthy after 40?
Choose habits that fit your circumstances: regular movement, nourishing meals, appropriate preventive care, social connection and supportive surroundings. Start with one action you can repeat. A birthday alone does not determine what you need.
